RESULTS: We included 13 eligible studies, providing data on 14 treated groups in 247 patients. The mean age of these patients was 34.5 ± 10.4 years, and female patients comprised 46% ± 12%. The mean duration from the incident to the start of brace treatment was 6.9 ± 5.1 months. The mean improvement in range of motion during the course of treatment was 38.4° ± 8.9° (95% confidence interval, 39.5°-41.8°).
CONCLUSIONS: The current evidence strongly supports the use of static-progressive stretching 3 times 30 minutes per day in each direction as a first line of treatment in patients with post-traumatic and postsurgical elbow stiffness. If this treatment fails or if reasons for stiffness other than soft-tissue incompliance are identified, further surgical interventions should be considered.
